HAIR-STRAIGHTENING DEVICE.

Specification of Letters Patent.

Patented J an. 16, 1912.

Application filed January 16, 1911. Serial No. 602,951.

To all whom it may concern:

Be it known that I, ALBERT F. Cox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hair- Straightening Devices, of which the following is a description. y

My invention belongs to that class of devices known as hair straighteners, and relates particularly to an instrument for straightening hair and taking the curls or kinks out of hair that is naturally very curled or kinked, and has among its objects the production of a simple, convenient, satisfactory and eficient device of the kind described that may be operated by the user without discomfort or without requiring the services of an assistant. Any suitable preparation may be used if desired either before or after the straightening operation or during the same.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a side elevation of my improved device, a portion broken away to show the construction, the open position of the same being indicated by dotted lines. Fig. 2 is a plan view of one of the coperating parts. Fig. 3 is a cross sectional view of the same taken substantially on line 3 3 of Fig. 2. Fig. 4 is a side elevation of a modified construction. Fig. 5 is a cross sectional view taken substantially on line 5 5 of Fig. 4. Fig. 6 is a cross sectional view of a modified arrangement. Fig. 7 is a top plan of one of the cooperating parts illustrating a modified arrangement for securing the rolls in position, one of the rolls being shown in section, and Fig. 8 is a cross sectional view of another modified construction.

Referring to the drawings, in which my preferred form of device is shown, l and 2 represent cooperating mating parts, both of which are extended as at 3 and 4 respectively and the extended ends crossed and pivotally vprovided if desired for keeping them normally in the desired position., The two cooperating parts l and 2 are preferably formed or recessed as shown in Fig. 3 and closed at the ends as at 8 8.

Arranged within the parts l and 2, preferably longitudinally thereof, are one or more rotating rods or rollers 9 and l0, which =`are pivotally secured in position by means `of screws l1 or their equivalents provided `with extended parts 111 for rotatably supporting the rollers.

As most clearly shown in Fig. 1, the rollers 7 are extended as at 12 from the body of the roll, so that the entire end portions of the rollers do not bear against the walls 8, thereby reducing the friction.

In Figs. l, 2 and 3, I show two rollers, 9-9 and lO-IO, in-each part, the same being arranged so that one roller of one part is arranged between and coperates with the proximate rollers of the other part.

The parts l and 2 substantially inclose the rotatable rolls and as the device is drawn through a quantity of hair, the hair other than that being acted upon between the rotatable rolls is prevented from becoming entangled with or wrapping around the rotatable rolls, by the parts l and 2. Fach of said parts l and 2 is substantially semi-cylindrical in cross section, so that when the parts are brought together, a structure substantially circular in cross section is presented, which can be drawn through the hair with little friction or pulling of the hair.

Fig. 4 illustrates the use of non-rotatable parallel rods or bars 14 and 15, in place of the rotatable rollers or rods which are secured in the mating parts 1 and 2 by means vof screws 16. In the case where the nonso that the hair will easily slip through, as

hereafter described. To prevent too great a pressure on the hair, or for facilitating opening the device, I show a spring 17 arranged between the extensions 3 and 4t of the handles, it being understood that the same may be of any style and be applied. to the construction shown in Fig. l, if desired. Vhere rods are used instead of the rotatable `rollers previously described, I preferably form them cylindrical, or so that they have the convex .faces similar to the rollers.

In the construction shown in Fig. 6, I

show an arrangement of three rollers 18-18 similarly formed so that the angle of the rollers relative to the handles is changed some.

' In Fig. 8 is shown an arrangement of two rollers orrods, as the case may be.

-In operating the device the rollers or bai's are preferably heated to the desired temperature, byv any suitable source of heat, the mating parts l and 2 having been previously opened so as to facilitate the heating. Anv

l special preparation may be applied to the hair, either before or after using tliedevice, or during the using if desired, as before mentioned, but I do not wish to be understood as implying that the same is necessary. A lock of hair is then placed between the rollers or rods in the parts l and 2 and the parts closed and maintained closed by the desired pressure on the handles 6 and 7 the device is then drawn toward the free ends of the hair. If the free end of the hair is held by t-he user the straightener may be operated back and forth between the ends, thereby thoroughly ironing or inangling the hair so as to straighten it, but if the free end is not held, then the same may be moved up so as to engage the hair near the head, and then drawn away, the operation being repeated. The rollers being free to rotate, do not grip the. hair or engage it too firmly with an excess of pressure so'as to pull it out by the roots, or discomfort the user, but, on the contrary, roll back and forth very effectively, accomplishing the result desired. As

before mentioned, where the non-rotatable rods or bars are used, they are preferably highly polished to avoid excessive friction or' pull on the hair. The rollers or rods by vmentof the device is not interfered with or limited by the handle part interfering with the hair. ^However, I do not wish to be understood as limiting myself to any particular. arrangement of the rollers or bars, as theyV may be varied in position 'from that" By making shown relative to the handle. the 'mating parts recessed or box-shaped, as shown, the heat is maintained in the rollers or rods for a longer time than if th'eywere more exposed. v

It is, of course, obvious that the device may be s0 constructed that the rolls may be removed from the recessed parts for heating, in which case they might be either pivotally or slidably connected so that they could not .become separated or mislaid. (Construction not shown).

Having thus described my invention, it is obvious that various immaterial modifications inay be made in the same within the scope of the appended claims without departing from the spirit of my invention, hence I do not Wish to be understood as limiting myself to the exact form, arrangement, construction or combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secur by Letters Patent is 1. A device of the kinddescribed, comprising the combination of recessed coperating 2. A device of the kind described, comprising the combination of coperatingv mating parts each part being provided with a pair of rotatable rolls extending longitudinally thereof, said pairs of rolls being arranged to lie parallel in proximity to each other with one roll of each pair positioned between the rolls of the other pair when the mating parts are brought together, and means for bringing said mating parts together with the pairs of rolls in proximity to each other.

3. A device of the kind described comprising the combination of coperating mating parts, said parts being extended and crossed to form handles, and means for pivotally securing the extended parts together, each co-.

operating part being recessed and provided with a plurality of rollers rotatably mounted therein, the ends of said rollersnear the end walls of the recesses being reduced in size to lessen the friction between the ends of the rollers and said parts.

4. A `device of the kind described, comprising cooperating parts, each part including a hollow shell substantially semi-cylindrical signed my name in the presence of two subin cross section, and a roll mounted in the scribing witnesses. shell and extending longitudinally thereof,

and means for bringing said parts together ALBERT F' COX' with the rolls in proximity to each other to Witnesses: grasp a lock of hair therebetween. ROY W. HILL,
